Getting likes on older photos?

I've recently started growing an Instagram account associated with a very popular niche. My strategy was/is to upload on a daily basis at more or less the same times-evenly spaced throughout the day. The account is growing at an acceptable rate but as I acquire new followers they naturally gravitate towards the most recent images, leaving my earlier uploads virtually untouched in comparison. Has anyone else dealt with this?
I may be overthinking it but it is giving my account a very unnatural feel. Recent uploads getting 50+ likes while earlier uploads are stuck at 10 or even less. My instinct is telling me to use an iOS app to send likes to the earlier posts just to even things out but I am unsure if this is the right way to go about things. Perhaps deleting the older photos and re-uploading would make more sense?

note: when I say older photos I'm talking about photos that are 4-7 days old.

Any input would be appreciated!

Thanks,
Stansy

It usually happens when you're just starting on Instagram. When you like other people's photos, most likely they will like back yours and sometimes, not always, they will like back the old photos as well.

I do the follow/unfollow method to gain followers and I like a lot of photos to get likes on my photos.

Do you go for the precision of manually liking or do point a bot in a certain direction and let it go wild?

I only did it manually for a week. I use FollowLiker to follow/unfollow 1000 - 1200 accounts, like 1500 - 1800 photos per day.
